Bye Bye Pentax.
I have k5, 6 lenses (2 Pentax, 2 Sigma, 2 Tamron) and 2 flashes (Pentax FGZ 560). And I have got hope I can develop with my favorite mark, idea - Pentax> For 3 years I am waiting for FF. It's bacame a synonim of developing and acarring about customer. Now, after news I have heard from competitors I must say "Good Bye". No chance for FF bodies in near futere. Even so -no lenses, high price in the begining. Nikon and Canon present new "cheap" bodies. It is no matter at all but they show they care about their clients. And that they are growing - not waiting for special chances, or any thing else like Pentax.
Bye bye Pentax.
BTW - I love my K-5

I realize it doesn't mesh with the line on the roadmap itself (which appears to be ~12-28mm), but might the DA wide zoom finally be the Pentax version of Tokina's 11-16mm f2.8 AT-X Pro DX that ultra wide angle shooters really should have already switched systems for?

That lens is so well regarded that a company actually sells a modified and reassembled version at a large (over five times) premium for the notoriously picky--not to mention, deep pocketed and to whom size and weight are not an issue--cinematographic crowd: the Duclos 11-16mm.

Do they actually sell? "Current wait time: 5-6 months"

(Warning! Full Frame speculation ahead!:

It's also possible that it will be a port of Tokina's 24x36mm (or, incidentally and unimportantly, "Vista-Vision" in cine terms) version of said lens: the 16-28mm f2.8 AT-X Pro SD FX, the arrival of which on the roadmap [instead of the 11-16mm] would be enough of an indication of a 24x36mm body's imminent arrival that a little bit of fudging of the line on the roadmap would be in order.)

Far be it from me trying to appeal to your brand loyalties, but I think the assumption is that a Full Frame will be announced by spring if it's coming. After that, it was not one of Ricoh's top priorities.
